The Cluster klystron demonstration experiment

Abstract The cluster klystron is a new concept for providing a power source for future linear colliders. This type of klystron uses many parallel beams from magnetron injection gun sources inside a common solenoidal magnetic field. Since each individual beam has a low current, it should be possible to obtain high efficiency and after recombination of the beams, high output power. This paper describes the concept and preparations for a proof of principle experiment now underway at Brookhaven National Laboratory (BNL).
